New install of 3140. I already have CAM setup and now setting up CAS in OOB VG. Just want to make sure as cco doc statest E0 is trusted and E1 is non-trusted. However, 3140 has physical E1 and E2 interface.

1. Can I assume that physical E1 is actually cco docs equivalent of E0?

2. Assuming topology:

Core6506(Layer3)--trunkVlan99Only-2970switch--EndDevice

Do I put the 3140CAS in the following manner:

Core6506(Layer3)--(E1)CAS(E2)-2970switch--EndDevice

TIA
